With .NET, a class defines an object. Objects and object occurrences are fundamental to PowerShell, where cmdlets produce and consume objects. For example, the Get-Process command returns objects of the class System.Diagnostics.Process. If you use Get-ChildItem to return files and folders, the output is a set of objects based on the System.IO.FileInfo and System.IO.DirectoryInfo classes.
